Hollyland Cosmo C2 HDMI/SDI Wireless Video System (2TX + RX)
Two-Transmitter Kit — 1080p60 up to 3000' LOS, HEVO 2.0, FPS Booster, UVC/RTMP/NDI|HX
Overview
The Hollyland Cosmo C2 HDMI/SDI Wireless Video 2-Transmitter System transmits up to 1080p60 over long distances up to 3000' (914.4 m) line-of-sight, using two transmitters to a single receiver for flexible monitoring and signal distribution in studio or field production.
Operating across 5.1 to 5.85 GHz, the system automatically detects interference and seamlessly hops to a cleaner channel using HEVO 2.0 for an uninterrupted signal with low latency of about 33 ms.
The receiver adds modern streaming capabilities, including UVC via USB-C (with OTG), RTMP for direct live streaming, and NDI|HX over the network via RJ45. It also features an FPS Booster algorithm to convert lower frame rate inputs like 1080p24/25/30 to smoother 1080p60 outputs. Power options include DC input for all units, L-series battery plates on transmitters, and a V-mount plate on the receiver.
